Chapter 7 - final consideration for vent settings

Question 1

What is the equation for changes in RR to a desired PaC02?

Answer 1

(Known) - PaC02 x RR
over —————–
(Desired)- PaC02 x RR

Question 2

What is the equation for changes in Fi02 to a desired Pa02?

When do you not use this?

Answer 2

(Desired)Pa02 x (known)fi02
over —————-
(known) - Pa02
* not to be used in weaning

Answer 10

NPPV – if tolerated
Ventilation – support level based on patient
High Vt 12 – 15 mL/kg
High Inspiratory Flow Rates
Constant Flow or Descending Wave
Normal ABG ranges for this patient

Question 13

What are the symptoms for CHF?

Answer 13

Acute SOB, Chest Pain, Acute Pulmonary Edema

Question 14

What is the treatment for CHF?

Answer 14

*Medications
  Diuretics to reduce vascular fluid
  Improve cardiac contractility
*Guidelines
  NPPV if patient can maintain ventilation
  Avoid hypoxemia to prevent further cardiac work
  Normal ABG ranges for this patient
  Ventilator settings in normal limits
